Hi Arshiyan ,
1. Do I need to delete setup tables and refill and reload data into Info Cube: 0PUR_C01?
First check the data in the fields used in the routine in the PSA . If data is there then you need not delete Setup Tables.If not do repair full to bring data correctly till PSA .Then you can load it to cube to check whether routine works correctly or not. You can also test the routine by double clicking on the mapping of the same in Transformation.
2. What could be the reason of not having data into Key Figure: 0GR_VAL?
1. No data available for the fields used in the routine calculation.
2. Routine not working as desired.
3. How can I get data into Key Figure: 0GR_VAL and others as you can see in the above screen shot?
Follow as stated above.
Regards
Kamal
